LOOM-SHUTTLE.

SPECIFICATION forming part of Letters Patent No. 496,879, dated May 9,1893.

Application filed April 6,1892. Serial No. 428,086. (No model.)

To all whom it may concern:

Be it known that I, ALFRED ISHERWOOD, a citizen of the United States,residing at New Bedford, in the county of Bristol and State ofMassachusetts, have invented a new and useful Loom-Shuttle, of which thefollowing is a specification.

This invention, relates to loom shuttles; and it has for its object toprovide improvements for securing the cop-spindle within the shuttlebody and means for adjusting the same.

To this end it is the main and primary object of the present inventionto provide means for pivotally securing the spindle in place so that thedisadvantages of having the pivot pins working in the pin holes in theshuttle body are avoided. By continual usage the pivot pin holes in theshuttle body necessarily become enlarged so that the pin works looselytherein and will gradually work out of the holes so as to interfere withthe movement of the shuttle and cut and destroy the reed of the loom.The use of the pin pivot for the spindle also prevents the spindle frombeing adjusted so that the filling will run freely from the bottom ofthe spindle. It is to avoid these disadvantages and objectionablefeatures that the present invention is designed, and the samecontemplated improved pivoting devices, as Well as means for adjustingthe spindle so that it can be raised or lowered and still kept in astraight line to the eye of the shuttle, whereas in the event of notbeing able to adjust the entire spindle or at least both ends equally,the same must necessarily slant to a certain extent and prevent'thefilling from running freely from the spindle.

With these and many other objects in view which will readily appear asthe nature of the invention is better understood, the same consists inthe novel construction, combination and arrangement of parts hereinaftermore fully described, illustrated and claimed.

I In the accompanying drawings :Figure 1 is a vertical longitudinalsectional view of the loom shuttle constructed in accordance with thisinvention. Fig. 2 is a detail in perspective of the bearing plate orstep and one end of the cop spindle. Figs. 3, 4 and 5 are similar viewsof modifications. Fig. 6 is a detail sectional View of an additionalmodification ing for one end of the cop spindle L.

of the bearing plate or rest. Fig. 7 isa detail plan view of one end ofthe shuttle and the bearing devices therein.

Referring to the accompanying drawings: A represents a shuttle body ofthe ordinary general construction, and provided at one end and in thetop thereof with the circular recess B, and the adjacent recessed slot 0opening into the open body of the shuttle and said circular recess. Saidrecessed slot 0 is designed to receive the angular bearing plate or restD, which snugly fits in the bottom of said recessed slot and is providedwith the upwardly extending arm E, resting against the back wall of saidslot, and terminating at its upper end in the enlarged right angularlydisposed securing flange F, which, as illustrated in the drawings, issemicircular, so'as to snugly fit the circular recess in the top of theshuttle body at one end, and thus securely hold the body of the bearingplate or restsecurely within its recess, so that the same is preventedfrom displacement. Said flange is held firmly in the circular recess bymeans of the leaf-springG, resting in the top of the shuttle at one endover said recessed slot and having a circular head G registering withsaid circular recess over said flange, and is held in position by meansof the securing bolt H, passing through the shuttle and projecting intothe nut recess I, in the under side of the shuttle body at the same endand accommodating anut J engag-- ing the end of the bolt within the nutrecess. Thesaid bearing plate or rest D, is provided on its upperfacenear the longer shuttle body slot with the bearing recess K, whichis designed to pivotally support and form a bear- The said cop spindle Lis of the ordinary shape and terminates at one end in the rightangularly disposed flat head M, which is providedwith the off-standingtongue orhe el N, which takes into the bearing recess K, on said bearingplate or rest and is held firmly in position therein, by the spring Gbearing upon the upper end of said head, and thus providingapivotalattachment for the spindle within the shuttle body, which allows thesame to be moved in and out of the shuttle eye freely, while at the sametime avoiding the many disadvantages of having the pivot pin working inthe wooden body of the shuttle. The flat head M of the cop spindleprojects below one end of the bearing plate or rest, and is designed tostrike the lockingpin O, mounted to slide in the'body of the shuttle,and when said spindle isin its horizontal position within the shuttlethe pin is designed to be forced into the nut recess I, and against oneside of the nut J, within said recess, so as to prevent the same fromturning as will be readily apparent.

In order to provide for the free running of the filling from the spindleit may be necessary to adjust the spindle within the shuttle, and inorder to accomplish this, I employ an adjusting screw P, engaging athreaded perforation p, in the body of the bearing plate or rest D. Thesaid adjusting screw is provided in the top thereof with a slot/p, bymeans of which the same may be adjusted and terminates below the bearingplate or rest in a thin flattened head Q, which head rests upon thebottom of the slot 0 and is of the same width as the plate'itself, sothat the head prevents the screw from coming loose when the plate orrest is in position. By taking out the bearing plate or rest, the adjustin g screw can be set as desired to either raise or lower the entirespindle within the shuttle. spindle head and the bearing plate flangesecurely holds the samein any position in which it may be set, andeffectually prevents the spindle from ever becoming displaced from itsbearing, while at the same time the adjustment provides for adjustingthe spindle straight up and down so that one end thereof will not behigher than the other in the shuttle.

In Figs. 3 and 4 of the drawings, it will be seen thatinstead ofconstructing the bearing plate or rest, with the bearing recess K, thesame may be provided with the opposite perforated lugs R, between whichthe spindle end having the pivot pins B may be pivoted, or instead ofhaving the said lugs perforated the same may be provided with thebearing notches R within which may be seated the pivot pins R of thespindle head, so that the spindle, may be pivoted upon the bearing plateor rest in a substantial and equivalent manner to that alreadydescribed, and still avoid the many disadvantages of having the spindlespivoted in the wooden body of the shuttle.

A further modification is illustrated in Fig. 5 of the drawings in whichthe tongue or heel N, of the spindle is provided with a bearing recessS, which takes over the bearing lug T, projecting from the base and oneend of the bearing plate or rest, which construction is merely areversal of the construction de-' scribed, and illustrated in Figs. 1and 2, and attains the same ends.

It will be readily seen from the foregoing that the Various modificationillustrated and The shuttle spring bears down on the cut, is-

described all subserve the same general principle of pivotally securingthe spindle within the shuttle upon an adjustable bearing plate or restto accomplish the objectset forth.

Various modifications similar to those described will readily suggestthemselves to those skilled in the art.

A preferable modification of the bearing plate or rest D isillustrated'in Fig. 6 of the drawings. In this figure the main portionor step of the bearing plate or rest is provided in the rear end thereofwith a threaded socket d, which adjustably receives the screw pin e,projecting from the flanged arm E of said plate or rest. It will bereadily seen by this construction, that the said bearing plate or restcan be readily lengthened or shortened as desired, and that by havingthe same sectional, the step portion when worn out can be readilyreplaced without losing the entire plate, and further that by shorteningthe length of said plate or rest, the spindle will be raised, and viceVersa, lowered by lengthening the plate or rest.
